Formula

Formula
kW/m² = kcal/(hr·m²) × 0.001163

Multiply any value in kilocalories per hour-square metre by 0.001163 to obtain the value in kilowatts per square metre.

Worked example

Convert 1000 kcal/(hr·m²) to kW/m².

  1. 01Start with 1000 kcal/(hr·m²).
  2. 02Multiply by the conversion factor: 1000 × 0.001163 = 1.163 kW/m².
Result1000 kcal/(hr·m²) = 1.163 kW/m²

FAQ

What is the conversion factor from kcal/(hr·m²) to kW/m²?
1 kcal/(hr·m²) equals 0.001163 kW/m². To convert, multiply the value in kilocalories per hour-square metre by 0.001163.
How do I convert 1 kcal/(hr·m²) to kW/m²?
1 kcal/(hr·m²) = 0.001163 kW/m². For any value, multiply by 0.001163.
How do I convert kW/m² back to kcal/(hr·m²)?
Divide by the same factor — or equivalently, multiply by 859.8452. So 1 kW/m² = 859.845 kcal/(hr·m²).
When would I need to convert kilocalorie per hour-square metre to kilowatt per square metre?
Heat-flux conversions between kcal/(hr·m²) and kW/m² appear in radiative-heat-transfer analysis, furnace and reactor design, electronics cooling, and solar-energy calculations. W/m² is the SI standard; BTU/(hr·ft²) and kcal/(hr·m²) appear in US and legacy European datasheets.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
